Subject: AMD GPU splat and network error

Hi,

There's two problems that have started appearing with 6.0. They might be 
unrelated.


1) There is a repeating warning from AMD GPU in logs (see below).

Visually I don't see this causing other problems but in case this is 
related to the second issue..


2) Network connections start silently failing after the computer has 
been on for a while.

DNS requests start failing, downloads slow to a trickle and so on. 
Restarting the network hardware does not

solve this, only rebooting the affected computer helps.


Is there commonality that might cause both? Or are they two entirely 
separate things? It is a discrete graphics card

while the Ethernet controller is integrated on the motherboard so I 
don't see them being related on that level.


Hardware:

NIC: 03:00.0 Ethernet controller: Intel Corporation I211 Gigabit Network 
Connection (rev 03)
GPU: 09:00.0 VGA compatible controller: Advanced Micro Devices, Inc. 
[AMD/ATI] Vega 10 XL/XT [Radeon RX Vega 56/64] (rev c3)
